6 Claims.

This invention relates to a novel means of mounting a lock or latch bolt and outer casing within a cylindrical bore drilled in a door or the like, whereby the bolt is securely mounted in a door or similar object from the outside of the door and also can be renewed from the outside with a minimum of eort.

An object of my invention is to provide a novel lock or latch bolt mount consisting of laterally projectible means which are forced against or into the Wall of a bore formed in the door.

Another object is to provide a novel lock or latch bolt mount of the character stated in which the securing means for the mount also drawns the mount securely within the bore of the door,

thus preventing rotation and longitudinal movement of the mount.

Still another object of my invention is to provide a novel lock or latch bolt mount which is simple in construction, inexpensive to manufacture, eiicient in operation, and easy to mount without a mortise or face plate.

Other objects, advantages, and features of invention may appear from the accompanying drawing, the subjoined detailed description, and the appended claims.

In the drawing:

Fig. 1 is a side elevation of my lock or latch bolt mount with parts broken away to show interior construction.

Fig. 2 is a rear view of my lock or latch bolt mount, the actuating cam and screw being shown in sections.

Fig. 3 is a front elevation of my lock or latch bolt mount.

Fig. 4 is a side elevation of my lock or latch bolt mount with `parts broken away to show interior construction, and the bolt .being of the type used in connection with a releasing means.

Fig. 5 is a side elevation of the actuating screw and cam.

Fig. 6 is a top plan view of the same.

Fig. 7 is a side elevation of a modied form of lock or latch bolt mount with parts broken away to show interior construction.

Referring more particularly to the drawing, the numeral I indicates a cylindrical housing in which a bolt 2 is mounted. This bolt is slideably mounted in the housing and is usually spring pressed to an outward position; and if desired the housing may contain a bolt 3 to which a pin 4 is attached, the pin being connected to a suitable releasing mechanisrn such as the usual doorknob.

A cylindrical bore 5 is drilled in the door 6 and the housing I closely fits this bore and is 2 xedly held therein, as will be subsequently described.

A tapered shoulder l, on the outer end of the housing or casing I, fits against the outer edge of the door and holds the casing or housing against inward movement.

A wall 8 closes the inner end of the housing or casing I. l

One or more discs 9 are mounted on the wall 8 and as here shown there are two suchl discs. These discs are superimposed, and preferably, bear against or rest against the inner wall 8 substantially as shown.

The discsS are slotted radially, as shown at Ill.

A pivot pin II pivotly mounts the discs to the inner wall 8; and note that this pivot pin is eccentric to the center line of the housing or casing I.

A mounting screw I2 extends through the housing I, from front to rear, and this mounting screw is also eccentric to the center line of the housing. Alsothe mounting screw is outside of and adjacent to the bolt 2, as shown in Fig. 3.

A cam rider I3 is threaded to receive the threads of the screw I2, and this cam extends into the slot Ill and engages one edge of the slot so that when the cam is pulled inwardly relative to the housing I, the mounted discs 9 will be pressed laterally and outwardly against the wall of the bore 5.

The cam or wedge I3 may consist of a stamping bent from a flat piece of metal with tw'o tapered side walls and a threaded hole to receive the screw I2, substantially as shown.

The inwardly extending tips I4 of the cam or wedge bear against the threads of the screw I2, and thus when the cam is engaging the discs, these tips will be pressed against the threads of the screw acting as a lock to prevent loosening of the screw by movement of the mount.

The wall engaging surfaces of the discs 9 are angularly cut so that the tendency will be to pull the housing I inwardly and thus pressing the shoulder I tightly against the outer edge of the door.

In Fig. '7 the housing or casing I5 contains the usual bolt (not shown) and includes the outer shoulder I6 and the inner wall I'I.

A single disc I8 is provided with a hinged lip I9 which ts in the wall I1 and adjacent to the outer edge of this wall.

A screw 20 extends longitudinally through the housing I5 and is threaded into or attached to the disc I8 adjacent to the outer or swinging end of this disc. Thus rotation of the screw 20 will cause the disc I8 to move toward, or away from, the wall I1. On movement toward the wall l1,
